Our solar system's second largest planet Saturn has nearly 150 moons - and one of its biggest might be able to support life. Data from the 2017 Cassini mission has revealed that a liquid ocean on the moon Enceladus is the first outside earth to contain phosphorus, the so-called "missing ingredient" to sustain life as we know it.

So why does it matter? Dr Chris Glein, a planetary scientist and geochemist at Arizona State University, is one of the study's co-authors. He told Newsday's James Copnall why the presence of phosphorus could indicate life on the icy moon.
